Marker formats here hold the field to printable non-space ASCII, while ``socket.gethostname()`` reports whatever the kernel stores: a space, a newline that forges an extra marker line, or a byte no codec encodes, which Python hands back as a surrogate. A holder that publishes one raw writes a marker it cannot read back, and loses the lock to the first peer that ages it out as malformed. ``?`` is illegal in a hostname, so escaping it along with every out-of-grammar byte as ``?`` leaves a real name untouched and still keeps two hosts apart, which :func:`owner_is_stale` relies on to refuse to probe a foreign PID. An over-long name ends in a digest of the part cut to fit the limit. A bare cut gives every name that shares the kept prefix one identity, and :func:`owner_is_stale` would then probe a local PID for another host's holder. c3NK|]}|tvr t|nd|dyw)r 02xN)r chr).0bytes \/home/spazio/kingdom_calls/work5/transenv/lib/python3.12/site-packages/filelock/_identity.py zhost_name..!s1 00D $snDs#%zutf-8surrogateescapeN-r ) joinsocket gethostnameencodelenr rhashlibsha256 hexdigest)namekeeps r host_namer&s 77&&(//9JK D 4y##"77!;u+atDE{/A/A/C D N N PQgRg hij ;3ch|tk7ryt|sy|yt|}|duxr||k7S)a Whether the recorded owner is provably gone, so reclaiming its marker cannot detach a live holder. Fail closed: return ``True`` only when this process can prove the exact recorded owner is dead. A marker from another host cannot be probed; a live PID whose start token still matches, or whose token cannot be read, is the holder or is indistinguishable from it; a live PID whose start token differs is a recycled PID, so the process that wrote the marker is gone. PostgreSQL, Qt ``QLockFile`` and Mercurial all break a stale lock only on proof of death and treat an unreadable or foreign owner as still holding.
